CARPET-S WEEPER.

SPECIFICATION forming part of Letters Patent No. 418,280, dated December31, 1889.

Application filed March 21, 1889.

To all whom it may concern.-

Be it known that I, WALTER J. DREW, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and useful Improvements in Carpet-Sweepers, of whichthe followingis a specification.

This invention relates to that type of car is raised and loweredindependent of vertical movement of the sweeper-case by the swingingmovement of the sweeper-handle.

The invention has for its object to improve such carpetsweepers; tosimplify their construction and render the connection between the handleand brush-shaft more direct and substantial to better govern theposition of the brush-shaft; to avoid the use of plates slidingverticallyin guideways, which are objectionable, owing to friction, andto provide novel, simple, and efficient means for controlling thepressure of the brush on the surface traversed, and at the same timepermit the brush-shaft to be conveniently and quickly removed andreplaced when occasion demands'or is desired.

The object of my invention I accomplish by the features of constructionand combination of devices hereinafter described and claimed, referencebeing made to the accompanying drawings, in which Figure l is aperspective view showing sufficient of a carpet-sweeper to illustrate myinvention; Fig. 2, a longitudinal central sectional view of the same,and Fig. 3 a detail perspective view showing a modification.

In order to enable those skilled in the art to make and use myinvention,I will now describe the same in detail, referring to thedrawings, where- The numeral 1 indicates a sweeper-case,and 2 abrush-shaft having at each end a friction wheel 3, which in practice isdriven by the drive-wheels in any suitable or ordinary manner.

I do not deem it necessary to illustrate the dustpans and drivewheels ofa sweeper, since they may be of any known type and constitute no part ofthe present invention.

Thebail 4: of the sweeper-handle 5 is pro- Serial No. 304,186. (Nomodel.)

vided at its extremity with a pivot (i, journaled' :in a socket 7 in theend wall of the sweeper-case, so that the handle can be raised andlowered by swinging it in on the pivot. The bail is furnished with astud or pin 8, 5 5 located at one side of or eccentric to the pivot 6,and to said stud or pin is journaled the upper end of a link or plate 9,which at its lower end portion carries or is connected with aninwardly-projecting journal or bearing 9 that engages with thebrush-shaft in any suitable manner to permit the latter to be freelyrevolved. In the example shown' the journal or bearing is made as acylindrical pin fixed to the link or plate and entering a socket in theend of the brushrshaft. The link or plate is so constructed or made ofspring metal that it can yield laterally in a direction away from theend of the sweeper-caseto disengage the journal or hearing from thebrush-shaft, whereby the latter can be conveniently removed andreplaced. I have shown both ends of the brush-shaft similarlyconstructed and supported; but for the purposes of my invention I willconfine the description to one end.

The brush-shaft is capable of rising and falling, and it can be loweredas well as raised independent of any vertical movement of thesweeper-case by simply swinging the handle in the proper direction on orwith its pivotal 8o attachment to the sweeper-case.

In Figs. 1 and 2 thepoint of connection between the bail and the link orplate is below the axis of the bail-pivot 6,so that the brush is loweras the sweeper-handle is raised,and conversely, while in Fig. 3 thepoint of connection between the bail and the link or plate is above theaxis of the bail-pivot, in consequence of which the bruslrshaft will belowered as the sweeper-handle is lowered, and conversely. The latterarrangement is, however, not so convenient in use as the arrangement ofthe parts to lower the brush-shaft by the rising movement of thesweeperhandle.

To provide a very desirable sweeper embodying my invention wherein thedrivewheels may be located outside the end wall of the case,1 providethe horizontal elastic band 10, having its ends secured to the case andprovided at or near the middle of its 10o length with a vertical slot12, through which the journal or bearing of the link or plate extends toengage and support the end of the brush-shaft. The slot permits therising and falling movements of the brush-shaft, While the side edges ofthe slot guide and retain the journal orbearing.

By the lateral crank or eccentric stud or pin of the bail to which thelink or plate is journaled, I avoid providing the bail with an enlargedsegmentally-slotted plate, and by my invention I also avoid theemployment of a plate sliding vertically in guideways, which isobjectionable, owingto frictional contact of the plates with the guides.

Having thus described my invention, what I claim is 1. The combination,with a carpet-sweeper case and a brushshatt, of a pivoted bail, a linkor plate connected with the bail at one side of or eccentric to thepivot thereof, and a journal or bearing connecting the link or platewith the brush-shaft, substantially as described. 1

2. The combination, with a carpet-sweeper case and a brush-shaft, of apivoted bail having a lateral stud or pin at one side of or eccentric toits pivot, and a laterally-yielding link or plate hung at its upper endportion to the eccentric stud or pin and provided at its lower endportion with a journal or bearing detachably engaging the brush-sh aft,substantially as described.

3. The combination, with a sweeper-case and a brush-shaft, of atransverse band at each end, a bail pivoted to the case, alink or plateconnected with the bail eccentric to the bail-pivot, and a journal orbearing connecting the link or plate with the brush-shaft, substantiallyas described.

In testimony whereof I have affixed my Signature in presence of twowitnesses.

WALTER J. DREW.
